Patented Apr. 13, 1937 UNITED STATES SYRINGE OR APPLICATOR Herman B.Lermer, Newark, N. J., assignor to Hygienic Tube & Container Company,Newark, N. J., a corporation of New Jersey Application March 3, 1936,Serial No. 66,779

1 Claim.

This invention relates to applicators for applying medicaments to bodyorifices in a simple and convenient manner, more effectively than hasheretofore been possible.

One of the objects of the invention is to pr vide an exceedingly simple,inexpensive and practical device of the class specified, adapted topermit the application of a substantial, and if desired, a measuredquantity of medicament.

Another object of the invention is to substitute for the heretoforecommonly used materials, preferably but not necessarily, an unbreakable,flexible and preferably a transparent applicator formed of a material,a. cellulose product for instance, which will not be damaged whencleaned in hot water, or otherwise cleaned, and one which owing to itstransparency, enables the user to positively see the substance pass outthrough the applicator tube.

A further object of the invention is to so form one end of theapplicator tube that it will lend itself admirably well for releasablyconnecting the applicator tube to containers such as are extensivelyused for merchandising medicaments and jellies for feminine hygiene,which are made of yielding materials, so that the contained substancesmay be gradually forced out by pressing the sides of the containertogether.

A further object is the provision of a transparent tube having a pistonslidably mounted therein for insuring the complete discharge of theentire contents of the tube.

These and other advantageous objects, which will later appear, areaccomplished by the simple and practical construction and arrangement ofparts hereinafter described and exhibited in the accompanying drawing,forming part hereof, and in which:

Fig. 1 is a sectional view of a medicament applicator embodying myinvention,

Figs. 2 and 3 are similar views, of tubes embodying a further modifiedform of the invention, and

Fig. 4 is a fragmentary sectional view of a further modification of theinvention.

Referring to the drawing, there is shown a device for applyingsubstances to body orifices, such as the anal canal or the vagina,comprising a tube I preferably made of a flexible, transparent,non-breakable material; however, it should be noted that the tube can bemade of any suitable material, for noting the contents thereof, ifdesired.

Referring to Figs. 1 and 3, at each end there- 5 of, the tube I isformed of a transparent mate'- rial as above described, and the rod 4with its piston 5 is inserted in the tube so that it will slide freelytherein. The ends of the tube are then bent inwardly to form the roundedends 2 and the flanges 3 which prevents the rod and 5 piston frombecoming separated from the tube.

In Fig. 2 is shown a slightly modified form of the invention in whichthe tube I is formed from a cellulose material or the like, preferablyof a. slightly greater thickness than is necessary in 10 the devicedescribed in connection with Figs. 1 and 3. At each end of the tubeinternal shoulders I are provided upon which rest tight fitting ferrules8 which project slightly inwardly from the inner walls of the tube,thereby providing 15 stops to limit the movement of the slidably mountedpiston.

The inturned flange 3 at the upper end of the tube I forms a suitablebearing for the rod 4 which has integrally or otherwise attached theretoa 20 suitable knob 6 by means of which the, piston 5 and rod 4 canbe'moved lengthwise of the tube. Obviously, in applying or extruding thesubstance, the piston is forced to a position near the end of the tube,thereby causing the sub- 25 stance to be discharged therefrom.

In order that smaller quantities may be definitely applied with the samedevice, the tube may be graduated throughout its length.

It will be noted that the piston 5 is a short 30 distance from the freeend of the rod I so that when the rod is moved forward almost its entirelength, the free end I I will pass into the open ends ll) of the tube I,discharging any of the substance ,which might accumulate, therebyexpellingthe 35 entire contents from the device.

, InFig. 3 is shown another modified form of the invention in which thetube I has secured thereto in any desired or convenient manner a bulbousmember 9, or whichmay be formed integral 40 made of hard rubber or othersuitable material; 50

The tip 9 has its bore formed with a shoulder engaging the end of tubeI, so that the inner wall of tube I is flush with the inner wall of thetip 9' as shown in the drawing. A piston 5 is slidably mounted in tubeI, the piston being attached to ,55

a rod 4, which is of sufllcient length to enable the piston i'- to bemoved entirely through tube and tip 9' so that all substances can beforced out of the tube and tip entirely.

The foregoing disclosure is to be regarded as descriptive andillustrative only and not as restrictive or limitative of the invention,of which obviously an embodiment may be constructed including manymodifications without departing noted in the appended claim.

aovmve Having thus described my invention, what I claim as new anddesire-to secure by Letters Pat- 1 the ends thereof turned inwardly backalong and parallel to the inner wall 01 the tube to provide flangesserving as stops to limit the movements of the rod.
